Refrigerated Air Dryers

Refrigerated air dryers cool compressed air in a circuit system. The compressed heated air from your process enters the circuit, being pre-cooled by the air leaving the circuit. It then enters an air-to refrigerant heat exchanger where the air is cooled to 38°. This cooling causes the moisture to condense and is drained away. The outgoing air then enters an air-to-air heat exchanger, raising the temperature to keep your piping from sweating.

Desiccant Air Dryers

Desiccant Dryers, also called regenerative dryers, twin tower dryers or adsorption dryers, cool air by passing through a pressure vessel with an adsorbent media (activated alumina, silica gel, molecular sieve and others). This type of cooling brings the dewpoint down to -40° or below. When two desiccant cylinders are used, one cylinder is drying the air while the other regenerates. This operation is typically done via solenoid operated valves.
